8.2: Physics 3 Dimensions & Progressions

Unit 1

● Explore how heating and cooling iron, brick, and water adds or removes energy. See how energy is transferred between objects. Build your own system, with energy

● Energy Forms & Changes PhET Simulation

● I can evaluate the

strongest evidence to support the claim of the kinetic energy of an object changes as energy is transferred to or from the object.

8.2.4 Phenomena: Tsunami Waves

Objective

Overview

Materials

● Students will watch a video and make a claim about how wave height is related to energy level. ● What makes some sounds louder than others? Lights brighter than others?
